To all whom it'maty concern..-

Be it known that I, ANDREW WALLACE, Jr., a citizen of the United States, residing at South Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Car-Loading Apparatus, of which the following is a specification.

My invention relates to an improvement in the class of apparatus for loading box-cars by handling bulk freight-such as coal, ore, and grainin a car through the medium of a power-shovel, which is actuated by the power mechanism to distribute more or less evenly throughout the car from its center the material loaded into it and which is fed in a heap at such center from an adjacent bin or other supply-holder.

The object of my invention is to provide an apparatus for the purpose named (and which shall be equally adapted for use in unloading cars) which shall be readily and firmly adjustable into operative position without injury to the car and as readily removable and which shall involve simplicity of construction, rigidity, strength, and durability without being unwieldy.

Referring to the accompanying drawings, Figure 1 is a longitudinal vertical section of a box-car equipped with my improved apparatus shown in sectional elevation, the section being taken at the line 1 on Fig. 2 and viewed in the direction of the arrow; Fig. 2, a section of the same, taken at the line 2 on Fig. 1 and viewed in the direction of the arrow; Fig. 3,- a section taken at the line 3 on Fig. 52, viewed in the direction of the arrow and enlarged; Fig. 4, a section taken at the line 4 on Fig. 3 and viewed in the direction of the arrow; and Fig. 5 a section taken at the line 5 on Fig. 3 and viewed in the direction of the arrow. 7

A. is a railway-car of the ordinary box-car variety, adapted to be loaded and unloaded through door-openings Ct a in its sides.

B B are similar booms provided to afford adjustable and stable guide-supports for the sheaves and cables through the medium of which the power-shovel C is actuated, as hereinafter described. As its preferred construction, though not essential in matters of detail, each boom comprises two telescoping sections Z; Z), preferably of tubular metal, the section b of greater diameter having a head 5 at its outer end, in which is journaled a sheave c and on which'are loosely hung the pointed stake-bars d d, and the narrower section b is formed at its inner end with a stop-head, shown in the form of a fork D The extent to which the boom-section b may enter the section b is regulated by a stop-pin b adapted to be inserted through either of a series of holes 19 provided at suitable in tervals apart to enable the length of the boom to be regulated according to the length of the car in which the booms are to be used.

D is aframe or housing for the power mechanism E, shown as a suitably-journaled shaft 6 to be coupled with the driving-power (not shown) and carrying, opposed to each other, shiftable miter-gears f f, provided with lever mechanism g for shifting them to engage the one or the other witha 1niter-gearf on one end of a pulleyor drum 7L, suitablyjournaled on a support in the frame D. This frame may be portable to adapt it to be placed between the side of the building (not shown) from which the supply of the material is taken and the side of the car A, into which the material is to be loaded. The upper transverse timbers or bars ii of the frame D are provided on their inner sides with longitudinal guides, shown as grooves i,'to receive tongues j, provided on the outer surfaces of the side bars j of a supplemental sliding frame D, adjustably supported at the tongues j on the frame D in the grooves 2" to adapt it to be moved back and forth with relation to a car A brought into position for loading. The front bar or timber 7' of the supplemental rectangular frame D has journaled in it guide-sheaves la la and carries on its under side, at opposite sides of its transverse center, eyes Z Z on the ends of bolts passed vertically through the bar.

To apply my improved apparatus to its purpose, a car A to be loaded is brought into position on the track A and the supplemental frame D is drawn into the adjacent caropening a to protrude into thecar. The opcrating-cable F passes about the drum h of the power mechanism E, thence over guidepulleys m 'm, suspended from the top of the frame D, and through the supplemental frame-barj over the sheaves k k. The

booms B B are adjusted in place by sticking memberj of the sliding supplemental frame D, the forked heads b on the inner boom ends affording stops to prevent displacement of the booms by the strain exerted lengthwise upon them through the cable, the ends of which are passed over the sheaves c and are fastened, as shown, to the power-shovel O. The supplemental frame D is held in its adjusted positionby shoes n, embracing-the side timbers of the car-opening and supported on links n, extending from the supplemental frame. The apparatus is then in readiness to be operated asfollows, under the control of an operator, who may stand for the purpose in the housing D to manipulate the lever mechanism g: When the material to be loaded is heaped into the center of the car, as through a chute (not shown) from the supply source,

the lever g is operated to engage with the drum-gearf one of the gears ff to turn the drum h in the direction that will cause the cable F to drag the shovel O, and with it ma terial from the heap, toward the end of the car to be first loaded. The operator manipulates the lever to shift the gearsff back and forth, and thereby reciprocate the powershovel between the end of the car and heap of material until the latter is leveled and that section of the car has been loaded. Then the cable ends are unfastened from the shovel, which is thereupon reversed in its position between them to be dragged back and forth between the opposite ends of the car and the heap of material loaded into its center to be leveled. When the loading is completed, the shovel is unfastened for removal from the cable ends, the booms are taken down and removed, and after unfastening the shoes n the supplemental frame D is slid back on its support to free the car, which may then be moved on its track out of the way.

The more import-ant advantages of my improvement are principally due to the provision of the booms, which are readily adjustable in place without injury to the car structure and as readily removable, besides preventing undue strain of loading from being exerted against the carwalls, such as would be occasioned by attaching guide-sheaves for the cable to the walls, and to the provision of the adjustable frame for supporting the booms at their inner ends in a manner to cause them there to withstand the strain exerted through the cable in the car.

While I have described my improved apparatus in connection with its loading purpose it is equally useful for unloading bulk material from cars, and I desire to be understood as intending it also for that use.

Moreover, my improvement is not intended to be restricted to the particular details of construction shown and described, as they may be variously modified without departure ism and a shovel connected to the cable, of

a boom-support, and a boom fastened at its inner end to said support to extend thence toward an end of the car and provided at its outer end with means for removably fastening it in the car and with a sheave over which said cable passes, whereby the stress of moving the shovel on said cable shall be exerted lengthwise of the boom against said support at its inner end, substantially as described.

2. In a car-loading apparatus, the combination with the cable, cable-driving mechanism and a shovel connected to the cable, of booms formed of telescopicallyadjustable sections and carrying sheaves at their outer ends over which said cable passes, and adapted to be extended in the car from its opposite ends toward its transverse center and to be removably fastened in the car, each at its opposite ends, substantially as described.

3. In a car-loading apparatus, the combination with the cable, cable-driving mechanism and a shovel connected to the cable, of booms carrying at their outer ends sheaves, over which said cable passes, and stakes for fastening the booms at said ends to the car body, said booms being adapted to be extended in the car from its opposite ends toward its transverse center, and a support in the car near said center for the inner ends of the booms.

.4. In a car-loading apparatus, the combination with the cable, cable-driving mechanism and a shovel connected to the cable, of booms provided at their outer ends with heads carrying guide sheaves for the cable and stakes for fastening the booms at said ends to the car-body, said booms being adapted to be extended in the car from its opposite ends toward its transverse center, stop-heads on the inner ends of the booms, and a support in the car near said center for said booms at their said stop-heads.

5.,In a car-loading apparatus, the combination with the cable, cable-driving mechanism and a support therefor, and a shovel connected to the cable, of booms carrying at their outer ends guide-sheaves for the cable and adapted to be extended in the car from its opposite ends toward its transverse center and to be fastened at said outer ends in the car, and a frame adj ustably supported on said support for the cable-driving mechanism to be moved back and forth relative to the side opening in the car and forming a support for the inner ends of said booms.

6. In a car-loading apparatus, the combination with the cable, cable-driving mechanism and a support therefor, and ashovel connected to the cable, of booms carrying at their outer ends guide-sheaves for the cable and stakes for fastening the booms at said ends to the car-body, said booms being adapted to be extended in the car from its opposite ends toward its transverse center, stopheads on the inner ends of the booms, and a frame adjustably supported on said support for the cable-driving mechanism to be moved back and forth relative to the side opening in the car and carrying supports for the inner ends of the booms at said stop-heads.

7. In a car-loading apparatus, the combination with the cable, cable-driving mechanism and a supporting-frame therefor and a shovel connected to the cable, of booms carrying' at their outer ends guide-sheaves for ANDREW WALLACE, JR.
